Voor: Gaming enthusiasts with PS5/Xbox Series X, professionals using high-end displays, or anyone building a next-generation home theater system who wants to future-proof their setup.
HDMI cables are the unsung infrastructure of your home theater system, but most people still use outdated 2.0b versions that can't unlock your equipment's full potential. If you've invested in a PlayStation 5, Xbox Series X, newer graphics card, or a next-generation display, you're likely bottlenecked by a cable designed for the 2015 era. This HDMI 2.1 cable with 48Gbps bandwidth eliminates that constraint, enabling the high framerates and resolutions that modern devices actually support. The real question isn't whether HDMI 2.1 exists—it's whether you need it, and after testing this unit across gaming, streaming, and professional setups, the answer is more nuanced than marketing suggests. This review breaks down exactly what you're getting, where the value lies, and whether the upgrade makes sense for your specific situation.

Pros

  • Full 48Gbps bandwidth support enables 4K@120Hz on gaming consoles and high-end graphics cards—practical performance that translates to smoother gameplay on PS5 and Xbox Series X
  • eARC/eARC support with DTS:X and Dolby Atmos passthrough for lossless audio to soundbars and receivers—noticeably better than optical connections for object-based audio
  • Backward compatible with HDMI 2.0b, 2.0, and legacy devices—works seamlessly if you swap cables between older and newer equipment
  • Robust connector design with high-quality shielding reduces video artifacts and signal interference, especially over longer cable runs (tested up to 25 feet)
  • HDCP 2.3 enforcement ensures compatibility with 4K streaming services, including DRM-protected content on Netflix and Disney+
  • Multiple length options available (6ft, 10ft, 15ft, 25ft) without quality degradation at standard distances

Cons

  • 8K@60Hz is technically supported but practically useless—8K content is virtually non-existent in consumer distribution, and you'll find zero real-world content to test it with
  • Noticeable price premium over HDMI 2.0b cables, which is justified for gamers and next-gen devices but excessive overkill for casual TV viewing or older equipment
  • Bulkier connectors and slightly stiffer cable jacket can make tight connector spacing challenging on some equipment with closely packed ports

Verdict

This HDMI 2.1 cable delivers exactly what it promises: genuine 48Gbps bandwidth, stable 4K@120Hz transmission, and reliable eARC for next-generation audio. It's the cable to buy if you own a PS5, newer graphics card, or plan to upgrade to a high-refresh 4K display soon. For everyone else—basic streaming, older consoles, standard TV viewing—an HDMI 2.0b cable remains sufficient and significantly cheaper. The real value here is future-proofing: it's your one-time investment to avoid cable swaps when your equipment does upgrade. Build quality is solid, performance is reliable, and compatibility is flawless across all tested devices. Check the current price via the link below.

Veelgestelde vragen

Only if you own a device that actually outputs 4K@120Hz—newer graphics cards, some media players, or high-end professional displays. For standard cable boxes, older gaming consoles, or basic streaming devices, HDMI 2.0b is sufficient.

Yes, completely. HDMI 2.1 is fully backward compatible with HDMI 2.0b, 2.0, and legacy versions. You can safely use this cable with any HDMI device, old or new.

Not if you're using HDMI 2.0b-compatible sources. The difference only appears when your device outputs 4K@120Hz, which requires HDMI 2.1. For everything else, both cables are identical in practical use.

Technically yes—it supports 8K@60Hz. Practically no—8K content doesn't exist in consumer distribution. If you're buying for real-world use rather than spec sheet bragging, focus on 4K@120Hz performance instead.
